deeraj.patil(a)ibm.com has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/1232498?usp=email ) Change subject: close_fsal_fd: remove GLOBAL_FD on close from lru list. ...................................................................... close_fsal_fd: remove GLOBAL_FD on close from lru list. The previous logic skipped remove_fd_lru when ERR_FSAL_NOT_OPENED was returned (FD already logically closed). When doing release(), which internally calls the close_fsal_fd on FD already in closed state, this FD doesn't get removed from global_lru_list and is freed. This dangling entry is pickedup by the reaper thread causing unintented behaviour (Use-after-free).
